MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains a large number of external links, many of which are structured as numeric slugs and point to PDF files, indicating a link farm designed to attract search engine traffic. The document body mentions 'Zuma deluxe full download', suggesting a lure to download software. The presence of numerous external URLs, including 'http://exclusiveboutique.shop/uploads/1/3/0/6/130620728/130620728.html#zuma+deluxe+full+download', strongly suggests a malicious intent to redirect users to potentially harmful content or downloads.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
